Detail

Synopsis

Multiple vulnerabilities have been discovered in Pidgin, leading to the remote execution of arbitrary code, unauthorized information disclosure, or Denial of Service.

Background

Pidgin is a client for a variety of instant messaging protocols.

Description

Multiple vulnerabilities were found in Pidgin:

* Yuriy Kaminskiy reported that the OSCAR protocol implementation in Pidgin misinterprets the ICQWebMessage message type as the ICQSMS message type, triggering an allocation of a large amount of memory (CVE-2009-1889).

* Federico Muttis of Core Security Technologies reported that the msn_slplink_process_msg() function in libpurple/protocols/msn/slplink.c in libpurple as used in Pidgin doesn't properly process incoming SLP messages, triggering an overwrite of an arbitrary memory location (CVE-2009-2694). NOTE: This issue reportedly exists because of an incomplete fix for CVE-2009-1376 (GLSA 200905-07).

* bugdave reported that protocols/jabber/auth.c in libpurple as used in Pidgin does not follow the "require TSL/SSL" preference when connecting to older Jabber servers that do not follow the XMPP specification, resulting in a connection to the server without the expected encryption (CVE-2009-3026).

Impact

A remote attacker could send specially crafted SLP (via MSN) or ICQ web messages, possibly leading to execution of arbitrary code with the privileges of the user running Pidgin, unauthorized information disclosure, or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All Pidgin users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =net-im/pidgin-2.5.9-r1

Title: USN-886-1 -- pidgin vulnerabilities
Description: It was discovered that Pidgin did not properly handle certain topic messages in the IRC protocol handler. If a user were tricked into connecting to a malicious IRC server, an attacker could cause Pidgin to crash, leading to a denial of service. This issue only affected Ubuntu 8.04 LTS, Ubuntu 8.10 and Ubuntu 9.04. It was discovered that Pidgin did not properly enforce the "require TLS/SSL" setting when connecting to certain older Jabber servers. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. This issue only affected Ubuntu 8.04 LTS, Ubuntu 8.10 and Ubuntu 9.04. It was discovered that Pidgin did not properly handle certain SLP invite messages in the MSN protocol handler. A remote attacker could send a specially crafted invite message and cause Pidgin to crash, leading to a denial of service. This issue only affected Ubuntu 8.04 LTS, Ubuntu 8.10 and Ubuntu 9.04. It was discovered that Pidgin did not properly handle certain errors in the XMPP protocol handler. A remote attacker could send a specially crafted message and cause Pidgin to crash, leading to a denial of service. This issue only affected Ubuntu 8.10 and Ubuntu 9.04. It was discovered that Pidgin did not properly handle malformed contact-list data in the OSCAR protocol handler. A remote attacker could send specially crafted contact-list data and cause Pidgin to crash, leading to a denial of service. It was discovered that Pidgin did not properly handle custom smiley requests in the MSN protocol handler. A remote attacker could send a specially crafted filename in a custom smiley request and obtain arbitrary files via directory traversal. This issue only affected Ubuntu 8.10, Ubuntu 9.04 and Ubuntu 9.10. Pidgin for Ubuntu 8.04 LTS was also updated to fix connection issues with the MSN protocol. USN-675-1 and USN-781-1 provided updated Pidgin packages to fix multiple security vulnerabilities in Ubuntu 8.04 LTS. The security patches to fix CVE-2008-2955 and CVE-2009-1376 were incomplete. This update corrects the problem. Original advisory details: It was discovered that Pidgin did not properly handle file transfers containing a long filename and special characters in the MSN protocol handler. A remote attacker could send a specially crafted filename in a file transfer request and cause Pidgin to crash, leading to a denial of service. It was discovered that Pidgin did not properly handle certain malformed messages in the MSN protocol handler. A remote attacker could send a specially crafted message and possibly execute arbitrary code with user privileges

Title: DSA-1870-1 pidgin -- insufficient input validation
Description: Federico Muttis discovered that libpurple, the shared library that adds support for various instant messaging networks to the pidgin IM client, is vulnerable to a heap-based buffer overflow. This issue exists because of an incomplete fix for CVE-2008-2927 and CVE-2009-1376. An attacker can exploit this by sending two consecutive SLP packets to a victim via MSN. The first packet is used to create an SLP message object with an offset of zero, the second packet then contains a crafted offset which hits the vulnerable code originally fixed in CVE-2008-2927 and CVE-2009-1376 and allows an attacker to execute arbitrary code. Note: Users with the "Allow only the users below" setting are not vulnerable to this attack. If you can't install the below updates you may want to set this via Tools->Privacy. For the stable distribution, this problem has been fixed in version 2.4.3-4lenny3. For the testing distribution, this problem will be fixed soon. For the unstable distribution, this problem has been fixed in version 2.5.9-1. We recommend that you upgrade your pidgin packages.

Description: Updated pidgin packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5. This update has been rated as having important security impact by the Red Hat Security Response Team. Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously. A buffer overflow flaw was found in the way Pidgin initiates file transfers when using the Extensible Messaging and Presence Protocol (XMPP). If a Pidgin client initiates a file transfer, and the remote target sends a malformed response, it could cause Pidgin to crash or, potentially, execute arbitrary code with the permissions of the user running Pidgin. This flaw only affects accounts using XMPP, such as Jabber and Google Talk. (CVE-2009-1373)
